There are currently two fathers listed for Rabbi Avraham Ben Yekhiel, Gaon of Egypt
One is an obviously fake tree from Jaim.
The other appears to be plausible, but has some grafted on profiles further up the chain from Jaim.
Could be an easy fix: i.e. cut the completely fake parent profile here, and then look into the parents of Joseph ben Yakob haKohen Bar Saṭya, ABD, Gaon of Sura after.
